On-demand processing of Sentinel-1 data:

On-demand processing of Sentinel-1 data

Compare the data given the different options: ARD metadata, terrain correction?, sigma, gamma

OpenEO conversion to dB in the process graph.

openEO graph creation and processing for S1 data

  1. Open the connection with VITO back-end. Please use the openeo-auth tool to configure credentials. https://open-eo.github.io/openeo-python-client/auth.html#config-files-and-openeo-auth-helper-tool
  1. Define range of interest in time from Sentinel-1
  1. Apply the ARD compliant SAR processing.
  1. Visualize the openEO process graph.
  1. Create a new batch job on the back-end and ask to process it.

If our area of interest is small, we can also do a direct request, but this will not return the CARD4L json metadata.

If a batch job was used, we can get a description of the job and check its status.

Download results

CARD4L results contain STAC metadata and the requested image.

Here we simply download everything, for inspection.

Timeseries comparison

Next to requesting CARD4L backscatter data on SentinelHub, we can also generate Sigma0 backscatter on CreoDIAS.

Compute the mean value, for each timestamp. OpenEO can also do this for you.
